ISTANBUL - Two anonymous Twitter accounts used to release secretly recorded conversations implicating family and associates of Turkey's prime minister and senior government officials in a corruption scandal appeared on Sunday to have been blocked.

Twitter last week agreed to comply with a Turkish government request to close some accounts that officials said had breached national security or privacy regulations.

The two accounts - Haramzadeler and Bascalan - each had more than 400,000 followers, who now see only a red circle with a line through it and cannot access any tweeted material.
